SPECIFICATION forming part of Letters Patent No. 575,603, dated January19, 1897.

Application filed July 7, 1896. Serial No. 598,338. (No model.)

To aZl whom it may concern.-

Be it known that I, FRANK GUTTERIDGE, of Seaforth, in the county ofHuron, in the Province of Ontario, Canada, have invented certain new anduseful Improvements in Brick- Making Machines; and I hereby declare thatthe following is a full, clear, and exact description of the same.

The object of this invention is to construct the brick-making machine sothat during the operation the various parts constituting the feeding,pressing, and delivering mechanism will act consecutively in the orderabove named and develop a high pressure per square inch on the brick inthe mold and positively deliver it after its formation.

The brick-making machine consists of a suitable framework, a cross-shaftjournaled in the framework, a cam mounted on the said cross-shaft, aplunger or series of plungers sliding in suitable guides in the said.framework, a die or dies carried by the said plunger or plungers, anadjustable stop to limit the downward movement of the plunger in orderthat the feed of the material to the mold can be regulated by theoperator during the brickmaking process, a table or top for the saidframework, having an opening through which the said plunger or plungersare adapted to move when delivering the brick to the top of the table, across-bar slidingin suitable guides above the top of the table andadapted to be moved over the said opening during one portion of therevolution of the cam and to be carried entirely across the said openingto allow of the plungers delivering the bricks from thedies whentheplunger or plungers have reached the uppermost portion of their stroke,rods connected to the cross-bar and cross-shaft to apply pressure to thecross-bar while it is over the said opening, a feed-box or hopper movingabove the said top or table in conjunction with the said cross-bar, themouth of the hopper arranged to cover the said opening in the top ortable during one portion of the revolution of the cam and to be moved.entirely away therefrom during the remainder of the revolution of thecam, a spur-Wheel mounted on each end of the cross-shaft, a series ofpins secured to the inner side face of each of the spur-Wheels, a leverpivoted at or about its middle to the said top or table, a

link connected to the upper end of the lever and to the feed-box orhopper, the said lever projecting below the said table, a projectionbolted to each side of the hopper adapted to engage the pins on the sidefaces of the spurwheels in order that during the revolution of thespur-wheels the pins coming in contact with the said projections willmove the feedboX to carry its mouth away from the opening through thetop or table, the continued revolution of the pins coming in contactwith the lower end of the feed-dies, wheels or rollers connected to theunder side of the hopper to facilitate its travel, a driving-shaftjournaled in the framework, a pulley mounted on the said shaft by meansof which motion is imparted to it, two pinions mounted 011 the saidshaft, each adapted to engage with its respective spur-wheel, a balanceor fly wheel mounted on the shaft, a roller mounted on the lower end ofthe plunger adapted to travel on the cam, the whole device beinghereinafter more fully set forth,and more particularly pointed out inthe claims.

In the drawings, Figure 1 is a transverse sectional view through theentire machine. Fig. 2 is a cross-sectional view on the lines a a,Fig. 1. Fig. 3 is a plan view of the top or table. Fig. at is a viewsimilar to Fig. 1,

showing the operating parts in the opposite position to that shown inFig. 1. Fig. 5 is a side view showing the cross-bar, cross-shaft, andconnecting-rods. Fig. 6 is a view of the adj ust-able stop for theplunger.

Like letters and numerals of reference refer to like parts throughoutthe specification and drawings.

The machine consists of a suitable framework A, composed of a base a anda series of uprights or standards (numbered, respectively, 1, 2, 3, and4) secured to the said base. The standards 1 and 2 are oppositelyopposed to each other at what might be termed the front of the base A,and each of the standards 1 and 2 is provided with a suitablejournal-boxB for a cross-shaft. Mounted in the box Bis a cross-shaft O.Mounted on the crossshaft 0 between the standards 1 and 2 is a cam D.Form ed in the inner side face of each of the standards 1 and 2 abovethe cross-shaft O is a guide E, and working in the guides E is a plungerF. The lower end of the plunger F F is a slot H.

is provided with a roller G to roll on the perimeter of the cam D.Formed in the plunger Jo urn alcd in the framework is a vertical screw1, and mounted on the screw I is a vertically-adjustable stop J, whichenters the said slot H. The purpose of the stop J and screwl is to limitthe fall of the plunger F after the canrfaee has cleared the roller G.The top of the plunger F is provided with a series of dies L, which workwithin corresponding molds M, carried by the top of the standards.

The standards and 4 are oppositely opposed to each other at the oppositeend of the base to the standards 1 and 2. Each of the standards 3 and 4tis provided with ajournalbox N, and mounted in the journal-box N is thedriving-shaft O. Mounted on the top of the standards 1, 2, 3, and i is atable P. Formed through the table 1, above the molds M, is an opening Q.Mounted on the top of the table 1 is a hopper or feed-box R, the mouthof which is so located as to cover the opening Q through the said tableat one operation of the revolution of the cam 1). Connected to thehopper R is across-bar or pressure-bar S, each end of which is providedwith a spindle or pin T. Connected to each side of the table P,contiguous to the standards 1 and 2, is, a flange U, and formed in theside face of each of the flanges U is a slot V, which forms the guidesfor the pins. Connected to the ends of each of the pins T is a rod 5,fitted with an eye 6, which encircles a cam 7, mounted on thecross-shaft C, so arranged that when the crossbar is over the opening Qthe cam will cause the said rods to draw downwardly 011 the cross-bar.By means of this construction the cross-bar will rigidly resist thepressn re from the plunger when the cross-bar is moved to cover theopening Q.

Connected to the hopper It are a series of wheels \V to facilitate themovement of the hopper over the top of the table P. Mounted on each endof the cross-shaft C is a spurwheel X, and connected to the inner sideface of each ot the spur-wheels X are a series of pins Y, arranged atequidistant points from each other. Connected to the side face of thehopper R is a projection Z, against which the pins Y are adapted tostrike during the revolution of the spur-wheel.

Pivoted to the table P is a lever b, the upper end of which is connectedby a link 0 to the feed-box, while the lower end of the lever 11projects below the bottom of the said table. Mounted on thedriving-shaft O are two spurwheels (I, each of which meshes with itsrespective spurwheel X. Mounted on the drivingshaft O is a pulley c, bymeans of which motion and power are transmitted to the shaft, andmounted on the said drivingshaft 0 is a balance-wheel or fly-wheel f todevelop a centrifugal force to assist in driving the spur-wheels d.

The operation of the machine is as follows: Power and motion aretransmitted by means of a belt to the pulley c and from the pulley e tothe driving-shaft O and spur-wheels d, which in turn impart motion tothe spurwheels X and cause them to revolve in the direction indicated byarrows. The spurwheels X during their revolution carry the pins Yagainst the projection Z to move the hopper B into the position shown inFig. 4. When the hopper is carried into the position shown in Fig. 4,the lever Z) is in a substantially vertical position, and the pins Ycomin g in contact with the lever move it into the position shown inFig. 1, moving the hopper into the position shown in the same figure tobring the mouth of the hopper over the molds M, in order that thematerial within the hopper may be fed to the said molds. hen the mouthof the hopper is feeding the molds, the plunger F is resting on thelowermost part of the perimeter of the cam D, the top of the dies Lforming a bottom for the said molds. The brick-making material israpidly fed to the said molds, and before the roller G of the plunger Fcommences to travel on the rise of the cam the molds are supposed tohave received their full complement of material. One of the pins Y is soarranged that before the roller G commences to travel on the rise of thecam it will strike the projection Z and move the hopper R away from theopening Q and move the pressure or cross bar over it, allowing thehopper and the pressure or cross bar to remain in that position asuflicient length of time to allow of the rise of the plungersufficiently to press the material into solidified bricks. The rise ofthe cam is provided with a slight depression g, in order that after the,plunger has applied the pressure to form the bricks it will drop intothis depression and remove the pressure from the crossbar to allow ofthe crossbar being drawn easily across the opening Q, so that when theelevation of the plunger is continued by the increased rise of the camthe dies L will lift the bricks above the top of the molds. The returnof cross-bar to the position shown in Fig. 1 delivers the bricks ontothe top of the table to facilitate their removal either by h ind ormachinery. The fall of the cam is abrupt, in order that the plunger willsharply descend to open the molds to permit of their being refilled fromthe hopper.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-
